美国国家自动化公路网财团对圣迭戈和洛杉矶之间的1-15号公路的自动化项目,共耗资20亿美元,历时8年的研究,将于1997年8月全部实行自动化。该段公路全长12.8公里,各种车辆早晚异常繁忙,往返如流。新技术的开发利用,不仅能极大地缓解交通拥挤,大幅度降低交通事故,而且还将减少空气的污染。 据研究人员透露,在该公路主干线上将埋设9.2万块磁铁,每块磁铁直径2.54厘米,每两块之 The National Highway Network Consortium will spend $ 2 billion on automation projects 1-15 of San Diego and Los Angeles for eight years and will be fully automated in August 1997. The section of the road a total length of 12.8 km, all kinds of vehicles unusually busy sooner or later, from home. The development and utilization of new technologies not only greatly alleviate traffic congestion and greatly reduce traffic accidents, but also reduce air pollution. According to researchers, 92,000 magnets will be buried on the main road of the highway, each of which will have a diameter of 2.54 cm. Each two
